Review of recent advances of radioisotope power systems

The two major components of any radioisotope power system, or generator, are a radioisotope heat source and an energy conversion system. Heat is produced during the decay process within the heat source. This heat is partially transformed into electricity and the waste heat is transferred to space or the environment surrounding the generator.
